“…Diflubenzuron [l-(4-chlorophenyl)-3-(2,6-difluorobenzoyl)urea], the active ingredient of Dimilin 25W, is a chemical used to control numerous forest and agricultural pests and is most often applied by aerial spraying (Fischer and Hall, 1992; Retnakaran and Wright, 1987;Retnakaran et al, 1988). Diflubenzuron was selected for study because of its wide distribution, the potential for aquatic exposure from aerial spraying in forestry practices, the expansion of available data on the environmental persistence and distribution in freshwater ecosystems, and its unique mode of action.…”

“…Buprofezin (2‐ tert ‐butylimino‐3‐isopropyl‐5‐phenyl‐3,4,5,6‐tetra‐hydro‐2‐thiadiazine‐4‐one) is effective against a wide range of hemipteran pests, including Aonidiella aurantii, Bemisia tabaci, Nilaparvata lugens and Trialeurodes vaporariorum 11–16. Diflubenzuron [1‐(4‐chlorophenyl)‐3‐(2,6‐difluorobenzoyl) urea] is effective in the management of Cacopsylla melanoneura, C. pyri, Lambdina fiscellaria fiscellaria, Lymantria dispar and Spodoptera littoralis 17–21. IGRs are effective against several phloem‐feeding and sap‐sucking insects and thus are suitable candidates for integration into D. citri management programs.…”

Buprofezin and diflubenzuron effectively suppressed D. citri adult emergence. D. citri were more susceptible as early (first-third-instar) than late (fifth-instar) nymphs. Both IGRs inhibited egg production and egg hatch. Reduction in the number of subsequent offspring suggests reduced vertical transmission of Candidatus Liberibacter asiaticus, the pathogen thought to cause citrus greening disease. The present results indicate that both IGRs tested here should be effective tools for rotation in insecticide-based D. citri management programs.

The oil formulation of diflubenzuron (Dimilin 45 ODC) persisted for 10-12 weeks on the foliage of a conifer forest in an Atlantic-climate ecosystem. Within 22-30 days following treatment, 55-80% of the insecticide had been removed from the foliage. During this period, the concentration of diflubenzuron was higher than 370 ng g(-1). Aerial application at 56.3 g of Al ha(-1) resulted in deposition levels of the insecticide ranging from 867.5 to 1824.4 ng g(-1), depending upon forest characteristics. The results showed that aerial application is only a suitable technique for the treatment of forest areas with dense foliage and/or high tree density and no more than 15% of tree-free area. The only metabolite detected was 2,6-difluorobenzamide, and this persisted on foliage until the first rainfalls occurred. An empirical mathematical correlation was found to express the influence of meteorological variables--rainfall, solar radiation and temperature--on the persistence of the insecticide. These results suggested that degradation of diflubenzuron on foliage could be due to photodegradation. Some recommendations were made to optimize the deposition of the insecticide on foliage and to minimize its persistence and the off-site spray drift.
